I have a 2000 xj 4.0, will this motor fit? If so, does it require any modifications or is direct bolt on?
Asked by P-BO from on
P-Bo, the ATK NORTH AMERICA 4.7L Baja Stroker Jeep Engine will fit just fine. Hope this helps!

Asked by JOHN from OSSIPEE,N.H. on
Hello John, We do not offer a complete turn key motor. You will need to remove the bolt on parts off the old motor when installing an Atk replacement engine. If you have anymore questions feel free to ask, Thank you.

Hi BD-1 I checked with ATK on the application and they told me this will not fit the 1999-2001 XJ. Thanks

As the largest private label crate engine remanufacturer in North America, ATK has been around for over 80 years producing parts including high performance engines, transmissions and rear axles. When your Jeep needs an engine rebuild, an ATK remanufactured engine uses reverse engineering processes to virtually eliminate factory defects that hinder performance. One reason ATK is at the forefront of engines is their adherence to thorough cleaning and inspection techniques and their machining and magnafluxing capabilities. If staying out of the garage and out on the trail is a priority, rely on ATK to get your 4x4 up and running. Shop ATK NORTH AMERICA Now
